INTERNAL COMBUSTION ENGINE CLEANING DEVICE Filed NOV. '7, 1928 INVENTORWe BY t a? l ATTOR N EY Patented Dec. 30, 1930 PATENT FFICEy l FRANK F.COWHERD, OKF CHICAGO, ILLINOIS INTERNAL-COMBUSTION-ENGINE-CLEANINGDEVICE Application led November This invention relates to certa-in novelimprovements in internal combustion engine cleaning devices, and has forits principal object the provision of an improved construction of thischaracter, which will be highly eficient in use and economical inmanufacture.

The efficiency of internal combustion engines is greatly impaired bycarbon accumulations in the explosion chambers and by accumulationsaround the valve seats and around the guiding members for the valvestems. y

I have found that by introducing a suitable luidinto the cylinders ofsuch engines that these accumulations may be obvated and therefore, theefficiency of the engine may be maintained ata maximum. It is thereforethe salient object of my invention to provide a construction which willpermit the introducing of such a cleaning fluid into the combustionchamber of an internal combustion engine.

An object of my invention ancillary to the foregoing is to provide adevice through which airV may pass to pick up the cleaning Huid andconvey the same into the intake manifold of the engine.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will best be understood by vreference to the accompanyingdrawings wherein a preferred form of construction is shown, and which:

body portion Vwhich is preferably formed of a transparent material for apurpose to be set forth hereinafter. The member 10 is substantiallycylindrical in formation and at the lower end thereof, the bottom member11 is mounted, which preferably has an upwardly extending flange 12 thatengages the periphery of the body member 10. At substantially in themidpoint in the bottom member 11 on the inner side thereof a boss 13 isprovided o0 through which an opening 14 extends to the outer side of thebottom member 11 for a purpose to be set forth presently. A headconstruction 15 is provided which is mounted at the upper end of thecylindrical member 10 65 and this head construction 15 includes adepending flange 16 which corresponds to the flange 12. A supportingbracket 17 is provided which is employed in the mounting of theconstruction. An vaxially arranged bore 18 extends through the headmember 15 and terminates in a screw-threaded portion 19 at the inner'end thereof. A pipe member 20 has one end thereof connected in thescrewthreaded portion 19 and the opposite end thereof is rested on theinner surface of boss 13. A bolt member 21 is passed through the opening14 which screw-threadedly engages the inner surface of the pipe member2O and thus a differential clamping action is created so which serves tohold the bottom member 11 and head member 15 in position on the bodymember 10.

Into the outer screw threaded end portion y22 of the bore 18 a plugmember 23 is fitted. 85 An opening 24 extends axially through the plugmember 23 and this opening is of relatively restricted size so as to besubstantially capillary. Adjacent the lower end of the pipe member 20openings such as 25 are provided for a purpose to be set forthpresently.

An outlet passage 26 is provided in the head member 15 which opens intoa conduit 27 that is connected into the head member 15. A conduitstructure 28 connects the conduit C5 member 27 with the intake manifold29v of an internal combustion engine.

In operation, a vacuum is created in the intake manifold in a mannerwell understood in the art. This causes air to be drawn 1 1li Gilthrough the opening 24, passage 18, pipe member 20, and out through theopenings 25 `into theiinterioi' of the body'meniber l0.

Prior to this time the plug member 24 Will have been removed and thebody member l Will have been filled with a cleaning fluid having theproperties set forth hereintofore and I have found that kerosene isVtherein to Which members may be connected to connect said chamber withthe intake manifold of the internal combustion engine.
